Question

The cross-section perpendicular to the base but not through the vertex of a square pyramid will be a __________

(a) square

(b) triangle

(c) trapezoid

(d) rectangle

I have been asked this question in quiz.

My doubt is from Sections of Solids topic in section Orthographic Projection, Projections of Lines, Planes and Solids of Civil Engineering Drawing

Answer 1

Right option is (c) trapezoid

To elaborate: According to the question here (referring the figure), the green coloured line i.e. the plane, represents the axis away from the vertex through which the section is obtained. On cutting, the section obtained will be a trapezoid (shown by red dotted lines).
